I'm running full length functional lake pipes on my 58 Buick, just flexible exhaust from the headers joined onto the lakes. To say it's loud is an understatement, it's insane. I'm trying to set up a 4bbl I've just installed and am running the engine on my driveway, but it's starting to cause problems with my next door neighbours. What's the best way to silence them? The exhausts that is, not the neighbours. As much as I'd like to do the latter. I could get a motorbike baffle in the end where the flexi exhaust joins the start of the lakes, would this work? Or has the baffles got to go at the outlet end? Problem with that is the outlets are curved, so I'd need some sort of flexible baffle. The obvious answer is to cut the pipes just before the outlet, insert some homade baffles and weld the ends back on. Not too keen on this idea. Any help on this?
